In this quote from "Isla and the Happily Ever After" by Stephanie Perkins, the speaker humorously comments on the contrast between their perception of the other person's appearance and their behavior. They suggest that if the person weren't so small, adorable, and innocent-looking, they might be scared or wanting to escape from the situation.
The speaker also jokes that the current situation resembles a scene from a horror movie, specifically a "torture porn" film, implying that the circumstances or interactions might be more intense or intimidating than they appear on the surface. The quote captures a playful tone, mixing humor with a hint of concern about how others might perceive the scene.
